I have a custom control that inherits from the datagrid. As part of my
control, I add an EditCommandColumn in my controls Init event (I also set a
bunch of default properties in my controls constructor).
If I just leave all of the default properties alone, everything works fine.
Here is what the code looks like: <TAN:TABLEEDITOR id="myte" PageSize = "7"
MaxStringLength = "100" runat="server"/>
However, if I change any property with property viewer, my EditCommandColumn
(and other items) now appear in the design viewer. (see below).
Is it possible to turn this behavior off?
Thanks,
Scott

FYI,
I was able to stop this behavior by adding:
if (HttpContext.Current != null)
{
//Add my EditButtonCommands
//ItemStyle's
{
But I am hoping there is a cleaner way to do this.
Thanks,
Scott

Scott,
When you're building a custom control, both design-time and runtime need to
be taken into consideration. You may want to take a look at custom
designers and design-time attributes. What you did will work just fine, but
it does muddy up the code as you stated.
Look specifically at the ControlDesigner class and ControlBuilder class.
What you'll need to do is derive from ControlDesigner and override
GetDesignTimeHtml() method and GetRenderHtml().
What that does for you is keeps your Render() method clean and concentrated
solely on runtime.
Chapter 9 of Wrox's "Professional ASP.NET Server Controls" dives in depth
into what you're trying to do.
